Turns out it's not quite that simple...   I just didn't let it run
long enough.

$ make
Linking CXX executable AstroMenace
c++: `/usr/bin/sdl-config: No such file or directory
make[2]: *** [AstroMenace] Error 1
make[1]: *** [CMakeFiles/AstroMenace.dir/all] Error 2
make: *** [all] Error 2

but of course it's present.

CMakeFiles/AstroMenace.dir/link.txt
is our culprit.

If you look at that file, the line length is huge (>10k characters).
The `sdl-config --libs` is not getting evaluated in a shell, like the
code expects, it's being evaluated by /usr/bin/c++, which of course
fails.

Short story is, the invocations of sdl-config --libs   and sdl-config
--cflags should happen not quite as late as they are, but earlier,
where they can be evaluated and expanded by Makefile and not by c++.
